Example: Cooling

With the infrared sensor, the air conditioner can detect the activity level in a room and adjust the temperature

and humidity automatically, thus achieving the purpose of energy saving.

Press the INFRARED SENSOR button.

The infrared sensor automatically adjusts the

indoor temperature and humidity according to

the activity level in the room. However, the

temperature

e and humidity specified by the

remote controller remain unchanged.

•

The energy saving effect can be achieved only after the energy-saving temperature control function keeps

working

for more than 2 hours.

In the energy-saving temperature-control mode, the energy consumption saved by the air conditioner varies with

the activity level.

The infrared sensor detects changes to the infrared generated by human bodies. Therefore, the accuracy

of infrared

sensor may be affected negatively in the following cases:

··

The activity level is very low (reading, watching TV, etc.) or human bodies are blocked by a screen, cabinet, or glass board.

··

The indoor temperature is very high and exceeds or approaches the human body temperature (when the refrigeration

just begins).

··

The person wears thick clothes and turns his/her back to the air conditioner.

··

Curtains or plant leaves swing due to pet movement or airflow.

Low activity level

Low indoor temperature

•

The tracing function (Page 20) can further reduce the energy consumption.

After detecting that the person leaves the room for 30 minutes, the air conditioner turns to the energy-saving modes

according to the settings in the remote controller as shown in the right table, but the preset temperature and humidity

in the remote controller remain unchanged.

When the air conditioner works in powerful operation, setting the energy-saving mode will cancel the powerful operation.

DYNAMIC AIR DEFLECTION FUNCTION (TRACING/EVASION)

The infrared sensor can detect the position of people and automatically change the airflow direction.

Press the AUTO AIR DEFLECTION button to switch the air deflection

mode.

■How to change the detection speed of the sensor of the dynamic air deflection (tracing/evasion) function:

·

There are 2 detection speeds: “Standard” (by intervals of 15"–3') and “Slow” (by intervals of 1'–10').

·The remote controller is set to the standard speed by default.

·When the detection speed of the sensor is too high, set the detection speed to “Slow”

(when people and pets in the room behave frequently, resulting in frequent changes to the airflow direction).

·

After the dynamic air deflection mode is set, the sensor usually works once every 15 seconds to 3 minutes to

detect the position of the person and adjusts the airflow direction accordingly.

(The airflow direction does not change with the movement of human body immediately.)

·If the dynamic air deflection mode fails to achieve the desired effect, adjust the airflow direction manually.

·When the machine works in cooling, dehumidifying, or dry cool operation after the dynamic air deflection is set,

if the indoor humidity/temperature is very high, the left/right/upper/lower air deflectors may change their angles

to prevent drop of condensed water. After the temperature falls, the air conditioner returns to the dynamic air

deflection status.

Press the (STOP) button ·The settings are saved.

Set the detection speed of the sensor to “Slow”.

After the running stops, hold down for more than 5 seconds while pressing and holding .

·

At this time, the air conditioner beeps for signal receiving.

·Return to the “Standard” mode by repeating the above procedure (until the air conditioner beeps for

signal receiving).

In addition to “Standard” and “Slow” modes, you can also fine tune the detection speed of the sensor.
